Ventajas
They feed you once a week or so, like a pizza or something. They have parties fairly often, but that's only applicable to those who like to drink loads.
Desventajas
Rakuten Marketing is basically a collection of small businesses merged into one. This hasn't been done well at all. We're expected to learn so much, from so many different angels, covering the entire business. Management is uninspired, our Japanese CEO forces us to listen to his thoughts every week for a meeting, we also have to sit through a weekly update from every business unit. The hours are long, hardly any time to actually have your hour lunch break. It's fuelled by some weird mix of Japanese/American culture, the UK is an after thought. We have to play by their rules.
